Monitor Internet Computer canisters for

Canister Status is an aeon skill: Monitor Internet Computer canisters for control-plane changes - a new controller, a module-hash change (upgrade), or a canister going missing from the public index - and alert the moment one happens. Uses only the public IC dashboard API. Like every aeon skill it is one SKILL.md prompt file that runs unattended on your own GitHub Actions, on a schedule or when you trigger it, and sends what it finds to Telegram, Discord, Slack or email.

A canister's control plane changing is a security event: a new/removed controller can mean a takeover or key rotation, and a module-hash change is an upgrade - new code is now running. For a canister you depend on, you want to know the moment that happens, not next week. This skill watches the public control-plane facts and fires only on a change.

Every aeon skill takes one optional text input, var, set in aeon.yml or typed in when you run it by hand. It picks the target or the mode for that run.

Canister id(s) to watch, comma-separated (e.g. ryjl3-tyaaa-aaaaa-aaaba-cai). Empty = read the watch list from memory/topics/icp-canisters.md (a ## Watch list of canister ids); if that is absent too, exit silently. Pass dry-run to skip notify (state still updates).

No extra API keys or MCP servers. It runs on the model you connected to aeon (a Claude subscription token, an API key, or another login).

Easiest: open Aeon Connect, sign in with GitHub and turn on Canister Status. No clone, no terminal. To add it to an existing aeon repo from a shell, run:

Then switch it on in aeon.yml (the default schedule is filled in):

  canister-status: { enabled: true, schedule: "workflow_dispatch", var: "" }
